Research:
Astronomers revealed in the last decade that the substellar mass regime is densely and
continuously populated. Previously we knew only the Solar System planets in this domain.
The detection of hundreds of planets orbiting other stars than our Sun,
and hundreds of so-called brown dwarfs, which fill the gap in mass between planets and stars,
challenges our view of how are Solar Systems formed.
Through application of cutting-edge observing techniques and facilities,
I am observationally exploring the processes that
lead to the formation of planets and brown dwarfs.
